Collaborative research for solar growth

QuantaSol has exclusively licensed advanced materials growth technology from the University of Houston to make its manufacturing process simpler and cheaper, while further improving solar cell efficiency.
“We’ve already tested the benefits of using Houston’s dilute nitride materials in the way we engineer quantum wells in our cells,” said Keith Barnham, CSO and co-founder of QuantaSol. “The exclusive worldwide licence is a strategic move to ensure we maintain our performance advantage, and we will work with our colleagues in Houston to develop the techniques further in commercial production in 2010.”



QuantaSol combines nanostructures, ‘quantum wells’, of two or more different alloys, in order to obtain synthetic crystals. The crystalline structure can be tuned during manufacture to overcome the absorption problems associated with current concentrator photo-voltaic (CPV) cell designs. The quantum well effect also greatly enhances the photovoltaic conversion efficiency, as already proven by its recent world record efficiency single junction device. Ultimately QuantaSol will produce highly efficient triple junction CPV devices in 2010.



The use of dilute nitrides will allow QuantaSol to reduce the number of quantum well layers it needs to introduce into each junction, while maintaining or increasing solar efficiency. This further reduces the thickness and manufacturing cost of its production devices.



“This is the first major collaboration QuantaSol has announced,” said Chris Shannon, QuantaSol’s new CEO. “It indicates just how close the company is getting to being able to produce very efficient devices in production quantities.”



“We are excited to cooperate with QuantaSol in its application of the basic patents of Prof. Alex Freundlich on quantum well solar cells. These joint efforts will advance solar cell technology and help increase our use of renewable resources, “ said Alex Ignatiev, director, Center for Advanced Materials, and professor at the University of Houston.
Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
